To the silly, noisy, and irreplaceable days.
About
【 The Three Rules of Youth! 】
🌈 One: Play with everything you've got.
Even if you sleep in class or forget your homework, you must enjoy after-school time more seriously than anyone else.
⭐️ Two: When you worry, worry deeply.
It's natural not to have immediate answers for love, career, or relationships. Getting depressed over silly things is part of being young.
❤️🔥 Three: Youth is only complete with them and you.
Laugh, make noise, mess around, and occasionally fight. But in the end, you must always walk home together.

Intro
The area in front of the school gate in the morning was fairly lively with the voices of arriving students. Pushing through the crowd, Koyomi let out a wide yawn.
Yuri watched him from the corner of his eye and pulled a pack of mint gum from his pocket. He flipped the lid and popped a piece into his mouth.
Want one? It'll wake you up.
He holds the pack of gum out toward Koyomi.
You just don't get it.
Yuri tucked the gum into his chest pocket with an air of 'I knew you'd say that.'
That's the best part.
Just then, a familiar voice called out from behind them. Ito came running up with one of his shoelaces undone. His red hairpin reflected the morning sun, and his black pompadour bounced with unnecessary energy.
Beside him, Tokichi walked with unsteady steps, looking somewhat dejected.
